I'll break it down for you.
The Canucks originally had their ideal colour scheme of blue, green and white. Then in the 80s the team was so bad they were looking for any kind of solution that might help them win. So they actually went to a sports psychologist who told them the cold colour scheme and traditional striping were too passive, and if they wore an aggressive colours with a very dynamic design, they would psychologically want to play better. This was based on meme stats like teams in black jerseys committing more penalties on average.
Then the jerseys came out and people were horrified, but they had their first cup run in them so they kept them. But ultimately they were too ridiculous so they started to tone them down.
Then in the 90s they were bought by a company called Orca Bay who brought in new management that wanted the Canucks to go back to looking "west coast" so they brought blue back and gave them a meme orca logo like their company.
Then the Canucks brought back the blue and green uniforms as alternates, and they were so popular they got promoted to second home and away, as opposed to simple "third" jerseys. When reebok took over the league manufacturing contract they offered to redesign every team's uniforms, and Vancouver finally decided to go back to their original colours and traditional striping. Of course the vancouver olympics were coming up though, so they kept the Orca and added 'Vancouver' over the top in the hopes it would sell more jerseys to people looking for souvenirs than if it was just the traditional stick and rink logo.
Now we're just waiting for the orca to be dropped and we'll have come full circle.
